Portulaca plant named &#39;dpaz16&#39;

ABSTRACT

A new and distinct  Portulaca  cultivar named ‘DPAZ16’ is disclosed, characterized by large yellow flowers. The new variety has a compact, semi trailing growth habit and forms a dense plant. The new variety is a  Portulaca , normally produced as an outdoor garden or container plant.

LATIN NAME OF THE GENUS AND SPECIES

Portulaca oleracea

VARIETY DENOMINATION

‘DPAZ16’

BACKGROUND OF THE INVENTION

The new Portulaca cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Portulaca varieties for ornamental commercial applications. The cross resulting in this new variety was made during September 2008.

The seed parent is the unpatented, proprietary seedling variety referred to as Portulaca oleracea ‘PT-8-405’ The pollen parent is unknown, as the crossing resulting in ‘DPAZ16’ was an open pollination, with unidentifiable pollen parents. The new variety was discovered in June 2009 by the inventor in a group of seedlings resulting from the 2008 crossing, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar ‘DPAZ16’ by vegetative cuttings was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in July 2009 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DPAZ16’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DPAZ16’ These characteristics in combination distinguish ‘DPAZ16’ as a new and distinct Portulaca cultivar:

1. Large flowers

2. Compact and dense semi trailing habit

3. Flowers open early in the morning

Plants of the new cultivar ‘DPAZ16’ are similar to plants of the seed parent, Portulaca oleracea ‘PT-8-405’ in most horticultural characteristics, however, plants of the new cultivar ‘DPAZ16’ have a more dense plant habit, and larger flowers. Additionally, the new cultivar has more leaves than the seed parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DPAZ16’ are comparable to the commercial variety Portulaca ‘Summer Joy Yellow’ U.S. Plant Pat. No. 12,256. These Portulaca varieties are similar in most horticultural characteristics, including flower color and flower form. The new variety ‘DPAZ16’ differs in having somewhat smaller flowers, of a solid yellow, whereas ‘Summer Joy Yellow’ has a characteristic orange ring in the flower color. Additionally, ‘DPAZ16’ has larger leaves, a different angle of attachment of the flowers and a more compact plant habit than ‘Summer Joy Yellow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DPAZ16’ grown in a greenhouse, in a 13 cm basket. Age of the plant photographed is approximately 85 days from a rooted cutting. FIG. 2 illustrates in full color a close up of a typical bloom of ‘DPAZ16’. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘DPAZ16’ plants grown in a greenhouse during Spring in Gilroy, Calif. The growing temperature ranged from 14° C. to 30° C. during the day and from 10° C. to 23° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types.
